COMBINATION-LOOK.

Specication of Letters Patent.

Patented Dec. 24, 1907.

To all 'whom 'it m'a/y concern: i

Be it known that I, WARREN H. TAYLOR, of Stamford, in the county of Fairfield and State of Connecticut, have invented certain new and useful 1m rovements in Combina.- tion-Locks; and I o hereby declare the following to be a full, clear, and exact descri tion of the invention, such as will enab e others skilled in the art to which it appertains to .make and use the same.

M invention relates to an improvement in com ination locks, and particularly to means for detachably secur' the nested tumble-rs and tumbler curb inmliice.

Heretofore it has been the usual custom to thread the tumbler post and screw the nested tumblers and curb in place thereon. This is objectionable owing to the diiliculty experienced in getting the tumblers in proper position and at the same time have the drivmg pin on the cam properly connected with the ily on the inner tumbler.

The object of my invention is to overcome the objection above noted, and provide simple and effective connecting means between thelock casing and the tumble-rs, whereby the tumblers and curb properly nested, can be readily and quickly laced in proper position with relation to t e parts Wit-l1 which they cooperate.

M invention consists in the parts and 'com inations of parts as will be more fully explllained and pointed out in the claims.

the accom anying drawings Figure 1 is aviewin rear e evation of my improved lock the rear plate being removed. Fi 2 is a view in longitudinal section the rear p ate being in place. F ig. 3 is a. view in vertical transverse section taken through the tumbler ost, and Fig. 4 is an enlarged view showing t e spring latch mounted in the lock case and also show' U a section of the curb, and Fig. 5 is a view o the sleeve and curb removed and showing the tumblers, interposed washers and the seats for the tongues of the latter.

1 represents the lock case, and 2 the tumbler post ha a plain face on which the sleeve 3 secure to the tumbler curb 4 is journaled. The tumblers 5 are mounted to rotate, and are secured against movement endudse on the sleeve, and are rotated by the spindle 6 and connecting gearing in the usual and well known manner.

The tumbler curb 4 is provided with two 55 forwardly projecting lilgs 7 each ol which is provided on its outer face with a. shoulder 8 which engages a corresponding shoulder 9 on the lu s 10. These lugs 10 are secured respective y to the upper and lower sides of the lock case, and the shoulders thereon are so located as to engage the shoulders 8 on the lugs projecting inwardl-T froni the tumbler curb 4 and thus lock the sleeve 3 carrying the tumblers 5 against outward movement. The lug 1U located at the too of the case 1 e5 is recessed to receive the spring pressed sliding pin 11 which latter is provided with a tongue 12 mo U in a slot 13 formed in the lower face of said ug, and normally resting Within a slot 14 in the tumbler curb 4. 70 With the tumblers 5 seated on the tumbler post 2 and the shoulders 8 on the lugs 7 of the curb 4, engaging the shoulders 9 on the lugs 10 on the case, and the curb 4 locked against rotation by the tongue 12, it will be 'I5 seen that the tumblers willnbe positively retained in their proper positions with relation to the parts with which they cooperate.

'lo release the curb 4 and tumblers 5, it is simplv necessary to force the pin 1l for- B0 wa y, thus cari-yin the tongue 1'2 out of the slot 14 in the tum ler curb 4, and leaving the latter ree to be turned. By now turning the curb, the shoulders 8 on the lu 7 thereof will be disengaged from the sho der 9 of the lugs 10 on the case 1, which releases the nest of tumblers and curb and permits them to be removed, for changing or reassembling.

To replace the tumblers, the sleeve 3 is 90 placed on the post 2 and the curb 4 turned or partly rotated until the shoulders 8 engage the shoulders 9 and the tongue 12 enters the slot 14 in the periphery of the curb, thus locking the curb against any movement on the post. This construction provides a very secure attachment and accurate adjustment between the driving cam and the inner tumbler.

It is customary in locks of this kind to locate washers between the tumblers so as to prevent a moving tumbler from moving the next adjacent tumbler by its frictonal contact therewith. With the present construc-- tion the lugs 7 projecting from the curb pro- 105 vide convenient points for attachment of these washers 15. Each washer is provided with tongues 16 which rest within grooves 17 in thc inner faces of the lugs 7 and are thus prevented from turning and prevent be lifted from the lock case.

one mo tumbler from rotating an adjacent tulixlllr b frictional contact.

The cover p ate 18 of the lock is substantially the same as shown in Reissue Patent No. 10,518 granted to E. Stockwell, August 26thl .884 and is held in place and against .removal by the tumblers as disclosed in said patent, conse uently in order to get at the tumblers, it vll be ne to first set the tumblers, after which the back, or cover late can be moved in the direction of the olt and when clear of the hol lugs can en the cover plate is in place it is held so by the enment of the tongue 18 thereof with periperies of the tumblers and it is only when the gates 19 in the tumblers are set to aline with the tongue 18, can the cover plate be moved in a direction to disengage same from the 'lock case.

It is evident that many slight changes might be resorted to in the relative arrangement of parts shown and described without departing from the spirit and scope of my invention hence I would have it understood that I do not wish to confine myself to the exact construction of parts shown and described, but,

Having fully described my invention what -I claim as new and desire to secure by Letters-Patent, is:-

1. In a combination lock, the combination with a lock case and tumbler post, of a series of connected tumblers and a tumbler curb the latter whollly within the lock case, means carried y sai curb, engagingmeans on the lock case for locking the curb and tumblers in position on the post, and means for rotating the tumblers.

2. In a combination lock the combination with a lock case and tumbler post, of a series of assembled tumblers and a tumbler curb the latter being wholl within the lock case, means for holding sai tumblers and curb on the post, means for preventing the curb from rotating and means for rotating the tumblers.

3. In a combination lock, the combination wlth a lock case and tumbler post, of a series of nested tumblers and a tumbler curb mounted on said post the said curb being wholly within the loci: case means on the curb engaging means on the case for preventing the tumbler and curb from moving lengthwise of the post, a spring catch eaging the curb for preventing the latter om rotating on the post and means for rotating the tumblers. 4. In a combination lock the combination with a lock case and a tumbler post, of a-series of nested tumblers and a tumbler curb mounted on said post, a shoulder on a part grojecting from t e curb engaging a shouler on the case for preventing movement of the tumbler and curb endwise of the post a spring catch for preventing rotation of t e curb when the parts are assembled, and means for rotating the tumblers.

5. In a combination lock the combination with a lock case, and a tumbler post, of a series of nested tumblers and a tumbler curb mounted on said post, lugs projecting forwardly from said curb, washers interposed between the tumblers and eng 'ng said lugs, means for locking said cur against movement in the direction of the length of the post, means for preventing the curb from rotating on the post, and means for rotatin the tumblers.

6. he combination with a lock case and tumbler post, of a series of nested tumblers and a tumbler curb mounted on said post, lugs projecting forwardly from said curb, washers inte d between the tumblers and provided with tongues which rest in grooves in said lugs, means for preventin the curb from moving in the direction o length of the post, means for holding the 'curb' against rotation on the post and means for rotating the tumblers.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
